16F690 read/write

[louislouis]

Hello,
I need a little help with read and write to internal EEPROM in PIC16F690.

I try to write to adress 10, value 1

like:

led1 var portc.4
buton1 var porta.4
led1flag var bit

init:
low led1
let led1flag = 0

zac:
read 10, led1flag
if buton1 = 0 and led1flag = 0 then goto onled
if buton1 = 0 and led1flag = 1 then goto offled
goto zac

onled:
high led1
let led1flag = 1
write 10, led1flag
debounce:
if buton1 = 0 then 
pause 10
goto debounce
endif
goto zac

offled:
low led1
let led1flag = 0
write 10, led1flag
debb:
if buton1 = 0 then 
pause 10
goto debb
endif
goto zac

But the program stuck on read and the write instruction.
On 16F628 I use these commands and it works, on 16F690 I am doing something wrong. Please can someone to explain how use READ and WRITE instruction on this chip. Thanks.
